Abstract

Introduction: Extracorporeal Shock Wave Lithotripsy (ESWL) is one of the main choices in non-invasive therapy in urolithiasis. The success of ESWL therapy can be predicted from internal stone factors (size, location, number) and on the anatomy and abnormalities of the congenital urinary tract. Researchers wanted to know the assessment and characteristic of Extracorporeal Shock Wave Lithotripsy (ESWL) success rate in urolithiasis as a consideration for clinicians for urinary tract stones management.

Methods: This study used a retrospective descriptive design. Secondary data were taken from the medical records of urinary tract patients who received ESWL therapy at dr. Kariadi General Hospital, Semarang, Indonesia during the period 2012-2017. The variables seen were sex, age, size, session time, shock energy, unilateral/bilateral, opacity and anatomy location. After the data collected, we analyzed the prevalence of each variables with SPSS 21.0 for Windows.

Results: The incidence of urinary tract stones in male was 1.8 times higher than women. a) Most incidences were in 41-60 years-old group (64.7%).

b) Average stone size in men 12.34 + 2.96 mm while in women 12.47 + 3.06 mm.

c) ESWL sessions averaged 1.8 sessions / patient.

d) The use of shock waves between 615 - 5000 shock counter and energy 344 - 1500 Joule.

e) Unilateral stones were found to be highest in both sexes (64.3% in male and 64.7% in female).

f) The most sites of stone was middle calyx (36.9%).

g) Radiopaque stones were found to be highest in both sexes (88.2%).

h) The lowest success rate of ESWL on the stone located on the lower calyx (73.8%).

Conclusion: ESWL is safe and effective for urolithiasis but before choose on ESWL procedure it is important to consider the location, size and density of the stone that will influence the success rate of the therapy.
